Swing Analysis of a Golfer using Singular Value Decomposition

Abstract

In this study, we tried to analyze the relationship between golf swing and golf club weight based on cooperative action as the first step to design a club adapted to individual swing. For extracting cooperative action from golf swing, we conducted experiment of acquiring swing data. Subjects were two experienced golfers. In this experiment, subjects swung two clubs that differ the club weight. We measured two experienced golfers’ swings by motion capture system (VICON). We built observance matrix from acquired positional data and we conducted singular value decomposition (SVD) on this observance matrix. By conducting SVD, we extracted cooperative action as some independent modes. Then, we conducted Three-Way ANOVA to main mode. As a result, we reached the following conclusion that we could decompose a swing data to some independent modes.
